By the end of this chapter you will be able to

  • Say what a solid, a liquid and a gas are like, and how each one behaves in a container
  • Sort everyday materials into solids, liquids and gases
  • Use a table to count how many materials are in each group
  • Explain that a liquid keeps its volume but changes its shape when it is poured
  • Plan and read a fair test that compares the shape of the same amount of water
  • Explain why the features of a material are used to group it

You should already know

  • Materials and their properties, such as hard, soft, rough and smooth (Year 1 and Year 2 Science)
  • Changing shape by squashing, bending and twisting solid objects (Year 2 Science, Chapter 10)

Where this leads

  • Changing state when heated or cooled, and the water cycle (Year 4 Science, Chapter 7)
  • The particle model of solids, liquids and gases (Year 6 Science)
